Many astrologers analyze a chart wheel with multiple rings and in the rings there may be a natal chart, a progressed chart, transits, and another kind of progressed chart or directed chart, or a solar return or other kind of chart. There are many variations of these chart wheels and kinds of progressions and returns. Described below are many of these features that are available in Sirius, and we describe the features in three sections:

  • Progressed Chart Wheels and Calculations
  • Returns, Phase Angle Returns, Diurnals, etc.
  • Forecasting with Interactive Chart Wheels
You can click on the images below to see a larger version of the image. Progressed Chart Wheels and Calculations

Secondary progressions (also known as day-for-a-year progressions) are probably the most popular form of progressions but there are other kinds of progressions. Also, there are different methods for progressing house cusps. Note that these different methods of progressing houses are different even for the same house system (Placidus, Koch, whole sign, etc.) In order to meet the needs of as many astrologers as possible, Sirius offers a large number of progressions and methods of progressing houses. Because you set your default preferences, these additional choices do not slow you down or get in your way.

The methods available for progressing houses are Naibod in R.A., Solar Arc, Mean Sun, Time, Quotidian with Bija Correction, Quotidian without Bija Correction, Fagan-Naibod, Quotidian Mean Sun, and PSR (Progressed Solar Return) Method. Even most advanced professional astrologers are not familiar with all of these options but they are available if you want them. To learn about some of these progressed methods, you can watch the video on Different Methods of Calculating Progressed House Cusps. Also in Sirius's Help system we have documented the accuracy of these calculations by comparing the results produced with classic astrological works, and we explain how these methods are used by the astrologers who developed and promoted them. Sirius is much more than just a program that lists a lot of fancy options that you can select. We also provide information to show that the calculations are accurate and instructional material on how astrologers use the methods.

Note that there are many other kinds of progressed methods in Sirius such as the classical primary directions, Hellenistic time lords, etc. but these methods are used to produce listings and tables and not chart wheels. Here we are discussing just progressed and return chart wheels.


Multi-Ring and Multi Wheel Styles
A Multi-Ring wheel can have house cusps that are equally spaced are are drawn in the size of the house cusps in the inner ring. Zodiac sign areas may be included around the outer edge if desired. For BiWheels only you can also have each wheel have its own house cusps. You can also select a smaller wheel with an aspect grid or a larger wheel without a grid next to it in the same window. You can also select a Dial format (like a 90 Degree Dial for example) with an interactive dial arrow that you can rotate to show the midpoint structures that are formed. Some astrologers prefer separate wheels rather than multi-ring wheels and you may place up to four wheels in one window.

One issue with Multi-Ring wheels is the ability to see the minutes of the planet positions. For example, suppose that one planet is at 3 deg 01 min of a sign and another planet is at 4 deg 59 min of the same sign. The two planets are almost 2 degrees apart. On the other hand if one planet is at 3 deg 59 min and the other planet is at 4 deg 00 min the 2 planets are nearly in exact conjunction. Some astrologers use Multi-Ring wheels without the minutes of arc and this runs the risk of not being able to see what the actual orb of an aspect is. In Sirius all Multi-Ring Wheels by default include minutes and they are readable, but you can remove the minutes very easily and set this as your default if you prefer (although most astrologers do not choose to do this).

Note that it is very easy to put any charts in a Multi-Ring Wheel, such as one person's natal chart, and another person's progressed chart, or natal charts of 2 people and their composite chart, or the geocentric and heliocentric charts of the same person.

Returns, Phase Angle Returns, Diurnals, etc.
Natal and Phase Angle Return

Many astrologers are familiar with Solar and Lunar Return Charts. There are many variations of these charts that astrologers use. Some of these variations and similar kinds of charts are:

  • Planet returns such as a Mercury Return, Venus Return, etc.
  • A return of one planet to another, such as the transiting Moon conjunct natal Sun
  • A demi-return, etc: An example of this is the time that the transiting Sun is opposition natal Sun. You can easily select a series of returns such as, for example, the four returns of conjunction, waxing square, opposition, and waning square.
  • Precessed Returns: Calculated using sidereal methods but shown in the tropical zodiac
  • Phase Angle Return: When two transiting planets form the same angle as in the natal chart.
  • Diurnal Chart: A chart for the time you were born on any day. There are four variations of this chart: Same Time, Same Sun-Asc Angle, same Sun-MC angle, and same Sun-MC angle in right ascension.
  • Converse Transit: Chart for how old you but before birth.
  • Converse Solar, Lunar, and Planet Returns: The return occurring at the time before birth equal to the age at the time of the converse return.
  • Tithi Return: A return used in Vedic astrology which is a Sun-Moon phase angle return with either the Sun or Moon in same sign as in birth chart.
  • PreNatal Lunation, New Moon, or Full Moon
  • Conception Chart based on the rules of E.H. Bailey.

We plan to expand this section and make tutorial videos on many of these methods. If you need more information, let us know and we will add more information here or make some tutorial videos.

Forecasting with Interactive Chart Wheels

With the interactive chart wheel, you can view a Multi-Wheel and click a button to have the forecast date jump forward or backward by a day, a month, a year, or even a minute or second of time. You can also jump to a particular date, change the wheel style and the kinds of progressed charts used. In the QuadWheel you can include a Solar Return. The ability to interactively change all of these features is a wonderful feature for many astrologers.

Different astrologers prefer different tools. Most astrologers love the Time Line Format, for example, and also the AstroSignature Forecast. Some astrologers, however, prefer to view the MultiWheel and watch it change over time.

Transit-to-Natal BiWheel

Additional Features of the Interactive Transit-to-Natal BiWheel
A BiWheel with transits in the outer ring and a natal chart in the inner ring is perhaps the most common MultiWheel. This interactive BiWheel has an additional features that is not available in the other animated Multi-Wheels. You can find the next or previous aspect of a transiting planet to a natal planet. There are pull-down menus for selecting the transiting planet and natal planet and a place to enter the aspect angle and then you press the button to find the time of the aspect and the chart is updated to show this. Finding the exact moment of a transit-to-natal aspect is not critically important for most astrologers so this feature may not be needed by most astrologers but we did receive requests for it because it is important for some astrologers, so it is available.

Additional Features of the Interactive Wheel
An interactive wheel is similar to the interactive Multi-Wheels described above but it is simply a chart wheel rather than a MultiWheel. The Interactive Chart Wheel is used, for example, in electional astrology, or, in other words, finding the best time to do something. The additional features of the Interactive Wheel are that you can find the time when a planet ingresses into another sign, and you can save the chart data temporarily, name it, and recall it. This is a very handy feature as you choose between various possible charts. You can also see a list of planets making aspects to the Asc or MC and also which fixed stars are conjunct the angular cusps. You can also save the chart as a chart entry.

For example, you might find a chart that looks good so you hold (temporarily save it) and call it "Sun conj Asc" because it is the Sun conjunct the Asc that is one of the key things you like about it. Then you find that an hour later Jupiter trines the MC and there are some other things you like but the Sun is not conjunct the Asc, so you hold this one. Maybe you notice a third chart and you hold it. Now you call each one back to see what you think of them. Now you save the ones you like the most as chart entries! Then you exit the interactive chart mode and you have the charts as entries and you can study them, compare them to other charts, pull up different chart wheel styles and anything else that you would like to do with the chart.

Again, different astrologers work in different ways. Sirius is extraordinarily comprehensive in both the techniques available and the ways that you work with the program. For astrologers who like to work with chart wheels interactively or who may use different kinds of progressed and return charts, Sirius provides the power and flexibility to help you view chart wheels and interact with them in a way that is comfortable for you.
